Don’t Be Deceived

2 Thessalonians 2:1-12 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, 2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand. 3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; 4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. 5 Remember ye not, that, when I was yet with you, I told you these things? 6 And now ye know what withholdeth that he might be revealed in his time. 7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. 8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: 9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 11 And for this cause God shall send them strong delusion, that they should believe a lie: 12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.

Introduction: Can a Believer Be Deceived?

Believers can be deceived. Salvation makes us children of God, but it does not mean that everything we believe is automatically correct. A believer can misunderstand a passage, accept false teaching, or become confused and troubled concerning doctrine.

That is what happened to the believers in Thessalonica. Paul had personally preached the gospel to them. He had also taught them about the coming of Jesus Christ and the gathering of believers unto Him. In his first letter, Paul presented that truth as a source of comfort.

1 Thessalonians 4:16-18 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18 Wherefore comfort one another with these words.

Paul had given them a clear promise: Jesus Christ would return, the dead in Christ would rise, and believers would be gathered together unto Him. His conclusion was, “Wherefore comfort one another with these words.”

Sometime afterward, however, a false message concerning these events reached the church. Instead of resting in what Paul had taught them, the Thessalonians became shaken and troubled. Something intended to comfort them had become a source of confusion.

These were saved people who had heard the truth and had been personally taught by Paul. Yet false teaching concerning the coming of Christ still unsettled them. The fact that Paul needed to correct them demonstrates that believers can be deceived concerning doctrine. False teaching cannot take away our salvation, but it can take away the peace and confidence that come from understanding the truth.

Why Deception Is Dangerous

The Thessalonians were not disturbed by something they immediately recognized as false. Whatever they heard appeared believable. It sounded convincing enough to shake people who had already been taught the truth.

Deception does not normally introduce itself as deception. If every lie clearly looked like a lie, very few people would believe it. False teaching often appears spiritual. It may be presented by someone who sounds confident and knowledgeable, come from someone we trust, or be supported by an interpretation that sounds reasonable. A person may be correct about many doctrines and still be mistaken about another one.

When we hear a teaching, therefore, our final question should not be, “Who said it?” Our final question must be, “What does the Bible say?”

God gives us pastors and teachers to help us understand His Word, and we should listen carefully when the Bible is preached. But no preacher, teacher, church, or religious tradition takes the place of Scripture. Every person who teaches the Bible is still under the authority of the Bible, and every teaching must be examined by the Word of God.

This is especially important when studying Bible prophecy. People often create charts and timelines, identify people and events, and present their conclusions as though every detail were plainly stated in Scripture. The problem is not studying prophecy. God placed these passages in the Bible because He wants us to study and understand them. The danger comes when someone’s interpretation begins to carry the same authority as the words God actually inspired.

In 2 Thessalonians 2, Paul speaks about the coming of Jesus Christ, our gathering together unto Him, a falling away, the man of sin, the temple of God, a restraining power, Satanic signs, strong delusion, and the destruction of the Wicked one. Paul plainly reveals certain truths about these events, but he does not identify or explain every detail. We must distinguish between what the Bible directly says and what we believe it may be describing.

1. Believers Can Be Shaken by False Teaching

2 Thessalonians 2:1-2 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, 2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.

Paul begins by calling them “brethren.” He is writing to saved people. His subject is “the coming of our Lord Jesus Christ” and “our gathering together unto him.” These were truths he had previously given them for comfort, but a false message concerning these events had disturbed the church.

Shaken in Mind

Paul tells them not to be “soon shaken in mind, or be troubled.” To be shaken is to be moved away from a settled position. False teaching had disturbed their thinking and unsettled what Paul had taught them.

That is what false doctrine can do to saved people. It can create fear where there should be comfort, confusion where there should be confidence, and instability where there should be assurance.

This can happen when a believer hears a new teaching and immediately begins questioning everything previously believed. Instead of calmly opening the Bible and examining the claim, the believer becomes troubled by the confidence of the person presenting it.

We should not allow every unfamiliar teaching to shake our minds. When we hear something new, our first response should be to slow down, open the Bible, and examine what God has said.

Neither by Spirit

Paul identifies three ways this false message may have reached the church: “by spirit,” “by word,” or “by letter as from us.”

“By spirit” could refer to someone claiming to possess a spiritual revelation or prophetic message. This does not mean that the Holy Spirit revealed something false. It means the message was presented as though it came from a spiritual source.

1 John 4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.

John warns believers that not every spirit is of God and not every spiritual claim should be believed. Our responsibility is to try the spirits by comparing what is taught with the Word of God. No spiritual claim carries more authority than the written Word of God.

Neither by Word

The message may also have come through spoken teaching or a report passed from one person to another. Someone may have spoken confidently and claimed to know what was happening.

There is a problem when people elevate the words of a pastor above the authority of God’s Word. Confidence is not the same thing as truth. Spoken teaching must be tested by Scripture just like every other claim. We should never allow another person’s words to trouble us or control us when those words cannot be supported by the Bible.

Nor by Letter as From Us

The message may have been contained in a letter that claimed to come from Paul and his companions. Paul’s name would have given the message credibility, and the Thessalonians may have believed it because they thought it carried apostolic authority.

Paul was telling them not to believe a message merely because it appeared spiritual, sounded confident, or carried his name. The message troubling them was “that the day of Christ is at hand.” Paul was correcting a false conclusion concerning the coming of Christ and reminding them that certain events must occur first.

2. God’s Word Must Settle What We Believe

2 Thessalonians 2:3-4 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; 4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.

Paul gives them a direct command: “Let no man deceive you by any means.” It does not matter who brings the message or how convincing it sounds. No person should be able to move us away from what God has said. Paul answers the false message by giving the Thessalonians revealed facts that should settle their minds.

That Day Shall Not Come

Paul introduced the subject in verse 1 as the coming of Jesus Christ and our gathering together unto Him. When he says “that day” in verse 3, he points back to the event already under discussion.

Paul says that day will not come until a falling away occurs and the man of sin is revealed. If Scripture says that something must happen before the coming of Jesus Christ and our gathering unto Him, then we should believe the order Scripture gives us.

The Falling Away

A falling away is a departure from a position that someone previously held or claimed to hold. In this context, it describes a departure from biblical truth. This does not mean saved people will lose their salvation. It can include people abandoning sound doctrine, churches moving away from truth, and people openly rejecting the faith they once claimed.

1 Timothy 4:1 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils.

Paul describes people departing from the faith by accepting seducing spirits and false doctrines. That fits the context of 2 Thessalonians 2, which concerns spiritual deception, the rejection of truth, and believing a lie.

Paul does not tell us exactly how widespread this falling away will be or how long it will last, but he clearly tells us that a departure from truth must occur before that day.

We can see this kind of departure in our own time. Many churches have moved away from the true gospel. Many people have added works as a requirement for receiving or keeping salvation. Others use Christian language but want nothing to do with the God revealed in the Bible. We should not claim that every present example is the final fulfillment of this prophecy, but these departures remind us how easily people can move away from truth.

The Man of Sin Revealed

2 Thessalonians 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition.

Paul describes a particular individual. Calling him “the man of sin” identifies his character: he will be openly characterized by rebellion against God. Calling him “the son of perdition” identifies his end, because perdition refers to destruction.

This man will be revealed before Jesus Christ returns and believers are gathered unto Him. There will come a point when his identity and wicked character are openly manifested. We do not need to identify the man of sin before God reveals him. Verse 3 tells us that he will be revealed, and verse 4 explains what he will do.

2 Thessalonians 2:4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.

The man of sin will oppose God and deliberately set himself against God’s authority. He will exalt himself above every object of worship. He will not merely deny the true God; he will attempt to take the place of God. He will seek the worship, obedience, and authority that belong to God alone.

The Temple of God

There are a couple of different ways people interpret “the temple of God.”

Some believe Paul is describing a physical temple that will be built in Jerusalem. They understand the language literally because Paul describes an individual sitting in a temple and presenting himself as God. Other prophetic passages involving a sanctuary, sacrifices, and an abomination cause people to connect this verse with a future Jewish temple.

Others believe Paul is referring to a spiritual temple – the church or the sphere of professing Christianity – because the New Testament calls believers the temple of God.

1 Corinthians 3:16-17 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? 17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.

Under this interpretation, the man of sin takes a position of religious authority among people claiming to represent God.

We should be honest about what the passage does and does not tell us. If someone says that the Jews will certainly rebuild a third temple in Jerusalem, restart animal sacrifices, and then see the Antichrist enter that building and declare himself to be God, that interpretation may draw upon several prophetic passages. However, 2 Thessalonians 2 does not directly mention Jerusalem, a rebuilt temple, Jewish priests, or restored sacrifices.

We must be careful not to add details that God did not give us or present an interpretation with the same certainty as the words of Scripture.

Proverbs 30:5-6 Every word of God is pure: he is a shield unto them that put their trust in him. 6 Add thou not unto his words, lest he reprove thee, and thou be found a liar.

We may not know with certainty whether Paul is describing a physical temple or the spiritual temple, but we do know that the man of sin will attempt to take the place and authority that belong only to God.

The Restrainer

2 Thessalonians 2:5-7 Remember ye not, that, when I was yet with you, I told you these things? 6 And now ye know what withholdeth that he might be revealed in his time. 7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.

Paul had already taught the Thessalonians these things while he was with them. Their problem was not a lack of truth. They had been moved away from what they had already received. New teaching should not cause us to abandon established truth unless Scripture demonstrates that we were wrong.

Verse 6 then explains why the man of sin had not yet been revealed: something was withholding him. To withhold is to hold something back. Verse 7 expresses the same idea with the words “he who now letteth.” In the KJV, “let” can mean to hinder or restrain.

The basic picture is simple. Someone is preventing the man of sin from being revealed, and that restraint will remain until the restrainer is “taken out of the way.”

The Thessalonians apparently knew the restrainer’s identity because Paul had told them. We do not have that earlier conversation, and this letter does not name the restrainer. The Bible tells us what the restrainer does, but it does not specifically tell us who the restrainer is.

It is acceptable to say, “I do not know,” when studying the Bible. That is not a failure to believe Scripture. It is a refusal to add our words to Scripture. We know that the man of sin is restrained until the appointed time, even if we cannot confidently identify the one restraining him.

The Mystery of Iniquity

Paul says, “The mystery of iniquity doth already work.” Iniquity is wickedness or rebellion against God. The word “mystery” describes something that is not yet fully seen or revealed.

The final man of sin had not appeared, but the rebellion and deception that would characterize him were already operating. There is both a present working of iniquity and a future revelation of the Wicked one.

Christ Will Destroy the Wicked One

2 Thessalonians 2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming.

“That Wicked” is another description of the man of sin. When he is finally revealed, Jesus Christ will consume him with the spirit of His mouth and destroy him with the brightness of His coming. There will be no struggle between equal powers. Jesus Christ will destroy him.

God’s Word gives us the order of events and describes the falling away and the man of sin. It tells us what the restrainer does without identifying who he is. It leaves some details uncertain, but it clearly reveals the outcome. God’s Word must settle what we believe. We should not allow anyone to move us to a different position without Scripture.

3. Rejecting Truth Opens the Door to Delusion

2 Thessalonians 2:9-10 Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.

Verse 9 takes us back to the Wicked one before his destruction. Before Jesus Christ destroys him at His coming, he will deceive many people. Paul tells us where his power comes from and why people will believe his lies.

Power, Signs, and Lying Wonders

The coming of the Wicked one will be “after the working of Satan.” His power and influence will come from Satan, and his coming will be accompanied by “power and signs and lying wonders.” People may see things that appear impressive, supernatural, and convincing.

Something supernatural is not necessarily from God. A person may claim to have received a dream, vision, prophecy, or spiritual experience, but an experience does not become our final authority. Every spiritual claim must still be tested by the Word of God.

Deuteronomy 13:1-3 If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder, 2 And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them; 3 Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams.

God warned Israel that even if a sign came to pass, they were not to follow someone who led them away from the truth. The sign did not prove that the message came from God. The message still had to agree with what God had already revealed.

Someone may say, “I know this teaching is true because I had a dream about it.” Someone else may say, “This person must be from God because of the miracles connected with his ministry.” But no dream, experience, or sign has the authority to change what God has said. An impressive sign cannot make a false message true.

They Received Not the Love of the Truth

Verse 10 says that this deception works “in them that perish.” These people are not described in the same way as the believers in verses 1 and 2. The believers had been shaken and troubled by false teaching. The people in verse 10 are perishing because they rejected the truth that could have saved them.

Paul says, “They received not the love of the truth, that they might be saved.” Their problem was not simply that they had never heard the truth. The truth was available to them, but they refused to receive it.

The truth that saves is the gospel of Jesus Christ. Salvation is received by believing on Jesus Christ, who died for our sins, was buried, and rose again. The people described here reject that truth and remain among those who perish.

God Sends Strong Delusion

2 Thessalonians 2:11-12 And for this cause God shall send them strong delusion, that they should believe a lie: 12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.

Verse 11 begins with the words “for this cause,” pointing back to their rejection of the truth in verse 10. Because they refused to receive the love of the truth, God sends them strong delusion.

This does not describe God confusing people who sincerely desire to know the truth. It describes God judging people who have refused the truth He gave them. They chose the lie, and God gives them over to the deception they desired.

When Paul says that they will “believe a lie,” the immediate context includes the man of sin presenting himself as God and using Satanic signs to deceive people. The lie likely includes the claim that this man possesses the place and authority that belong to God. What we can say with certainty is that people who refuse God’s truth will accept Satan’s deception.

Verse 12 says that they will be “damned,” meaning condemned. They are condemned because they “believed not the truth, but had pleasure in unrighteousness.” They are not presented as innocent victims who desperately wanted the truth but could not find it. They rejected the truth because they preferred unrighteousness. Satan’s deception is real, but their deception does not remove their responsibility.

We must not reject truth in our own lives. A person who listens only to teachers who agree with him is vulnerable to deception. A person who refuses to reconsider what he believes when Scripture corrects him is also vulnerable. Loving the truth means allowing God’s Word to have the final say.

Conclusion: Search the Scriptures and Hold Fast to the Truth

This passage begins with believers who had been shaken by false teaching. Paul steadied them by reminding them of what God had revealed. He explained that a falling away would come, the man of sin would be revealed, and the mystery of iniquity was already working. Although we may not understand every prophetic detail, we know how the story ends: Jesus Christ will destroy the Wicked one at His coming.

Paul then warned about the terrible end of those who reject the truth and believe a lie. That leaves us with a simple question: How should we respond when we hear spiritual claims or teaching from the Bible?

Acts 17:11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.

The Bereans were willing to listen, but they did not accept something merely because a respected teacher said it. They searched the Scriptures for themselves to determine whether the things they heard were true. If Paul’s preaching was examined by the Word of God, every preacher’s teaching should be examined by the Word of God.

The more carefully we know the Bible, the less easily we will be moved away from what it teaches. Listen when the Bible is taught, but search the Scriptures for yourself. Do not treat another person’s opinion as though it were the Word of God. Do not preach speculation with the certainty of Scripture. Be willing to let the Bible correct what you believe.

Do not merely know the truth. Receive it, love it, and hold firmly to it. The best protection against deception is a heart that loves the truth and a mind settled upon the Word of God.

Do not be impressed merely by confidence, authority, or spiritual claims. Search the Scriptures. Hold fast to what God has said. Do not be deceived by man.
